You can, it's a little involved and in my opinion not really needed for our application and not worth the trouble to determine it thru the software. It's a fine tweaking on our trucks that not is as demanding as it is on gas engines.

I figured the exhaust was a good enough air/fuel gauge for a diesel.

If it smokes its a bit rich, if it doesnt then its probably just right or a little lean.
